You: Let's solve climate change mitigation through technological innovation while keeping aesthetics in check with our advanced JavaScript algorithmic approach. We aim to construct a tool which not only enhances the user experience by providing interactive, data-driven recommendations for curcursors and also supports local weather information retrieval via an external API from OpenWeatherAPI using their OAuth2 authentication method. The tool will be capable of determining whether your current location is at risk of extreme weather events based on the real-time weather conditions supplied by the API, with consideration given to areas with a history of such incidents in the past five years. It must employ user-friendly design principles and be compatible with both desktop and mobile devices.
